With 800 psi potential pressure 'driving' the discharge brine it really makes no difference of a few static height of discharge. Each 2.31 feet of static height of water is equivalent to 1 psi pressure .... pretty minuscule when the high pressure pump is 'driving' at up to 800 psi.

But the discharge line that runs to the thru-hull fitting isn't running at 800 psi, is it? I'm fixin' to install a watermaker in our boat. I've skimmed the instructions a couple times now and I haven't seen the location of the discharge fitting as a concern. The advice I've heard from other folks that have installed one is that it's good to be able to see the discharge and IIRC, it's to confirm that it's running properly.
